Wow! Great thread! My factory favorites are the Magnum 500 style, be it from Mopar, GM, or Ford. Next is the Mopar rally wheel from the Dart/Duster. My third favorite is probably the Oldsmobile super stock wheel that can be had in body color. I had those on a '74 Oldsmobile Omega S.
My aftermarket wheel of choice is the Keystone Klassic. Second place goes to the Kelsey-Hayes wire spoke wheels.
